Methyl iodide → 4-Chloro-7-(methoxymethyl)-5,6,7,8-tetrahydroquinazoline

Participants

Reaction Steps

To a slurry of (4-chloro-5,6,7,8-tetrahydroquinazolin-7-yl)methanol (reagent preparation 42, 0.80 g, 0.40 mmol), potassium carbonate (0.11 g, 0.81 mmol) and THF (15 mL) was added iodomethane (0.09 mL, 0.60 mmol). The reaction mixture was stirred for 18 hours and then partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over magnesium sulfate, filtered and concentrated in vacuo. Purification by silica gel chromatography provided 4-chloro-7-(methoxymethyl)-5,6,7,8-tetrahydroquinazoline (0.03 g, 35% yield) as a waxy solid. MS (ES) for C10H13ClN2O: 213 (MH+).
